Gary Ablett says he was never informed of his release from Stockport County.
Ablett told BBC Radio Manchester: "I haven't been involved at all in the decision, the new consortium have never spoken to me."
But chief executive Sean Connelly said Ablett had left the club on good terms.
The ex-Liverpool youth-team coach appeared to have a different view, as he added: "I do feel mistreated as the courtesy of a phone call would've been nice.
"But obviously that hasn't happened and I think I've known this day's coming over the past four to six weeks, possibly even longer, with the fact they haven't spoken to me.
"Do I regret going to Stockport is a difficult question," he added. "I did have other offers on the table at the time and certainly I had a very good offer to go and work abroad on a three-year contract."
